Melissa Cavello came in for an appointment concerning a severe break out of acne covering her face and shoulders. Background information for her includes fourteen years old, no allergies, no previous diagnosis, vital signs were normal were within normal range, weight being 135lbs, and acne has become progressively worse over the past three months. Her history includes that she has visited multiple other doctors that have only ruled out any hormonally issues that may result in acne. The doctor…

HALDANE RELATIONSHIP AND ONE-WAY ENZYMES  INTRODUCTION: Most of the enzyme catalyzed biological reactions are reversible in nature. However, an enzyme may prefer to catalyze the reaction more efficiently in one direction over the other under given physiological concentrations of substrate or product (substrate in the reverse direction). An enzyme favouring a virtual unidirectional catalysis of an overall reversible reaction can’t escape the laws of thermodynamics. As a catalyst doesn’t change…

In recent studies, cyanide poison is a toxic substance that appears in different variety of crops. According to Ogundele and Caxton- Martins," Cassava is the most widely consumed of these plants and it has been associated with economic condition in certain parts of the World; especially the tropics and sub tropics." These plants are called cyanophoric plants because they contain phytotoxins. Cyanide is very highly reaction to alkali earth metal. They mostly reactive to salt such as potassium,…

The hypotheses given were greatly supported during the experiment. Three of the four drugs; Lignocain, Hexamethonium, and Atropine, all showed a decline of inhibition of peristalsis. Nicardipine showed to have complete inhibition of peristalsis. It showed to have a 0 au drug amplitude. There were two standard pressures for this experiment. This was due to the two groups having to compensate for the differences in the two tissues used. Pressures used for Hexamethonium and Nicardipine was 2 cm/H2O…

The purpose of this study was to investigate the effect of a system that automatically adjusting hydrogen peroxıde Colloıdal-Ag dose to reduce colonization and growth of heterotrophic bacteria in dental unit waterlines and wastewaters. Thirty dental units were assigned into three groups with respect to the protocol employed: Group 1: 10 units were selected for automatic administration. Group 2: 10 units were selected for manual administration and Group 3: 10 units served as controls. Water…

It is also called anabolism or biogenesis. It is a enzyme-catalyzed method in which substrates are transformed into complex products. In this process simple compounds change or convert into other compounds or they join together to form macromolecules. Example: In this process gluneogenesis is responsible for the production of glucose from non carbohydrate originator. Actually biosynthesis is an enzyme-catalyzed process in which substrates are converted into complex compounds. 1. Biosynthesis…

Practical 3: Enzyme Activity (2.5) Research Question: How does the change of pH affect the rate of decomposition of hydrogen peroxide on the enzyme, catalase? Background Information: Enzymes are globular proteins, which are synthesised by cells in order to perform specific functions. These act as catalysts in chemical reactions and are considered a major factor in an organism as these reaction rates are required to be shortened in order to support life. Catalase is one of the most…

and 1 mL of catalase. We then waited the indicated period of times on the cups, which is our independent variable, to put the sulfuric acid (H2SO4) in to the cup to stop the reaction. We then added KMnO4, drop by drop, to see how much hydrogen peroxide remained in the solution, which was our dependent variable. An enzyme is a catalyst, and it has two fundamental characteristics that it is known for. One of these things it that it can increase the rate of a chemical reaction without being…

poisonous chemicals, hydrogen peroxide. In the lab we used multiple reactants, temperatures, and pH levels. For the tissues and enzymes we used livers, new, used, cold, warm and boiled, chicken breasts, potatoes, and apples. We also used hydrogen peroxide, warm and cold, acidic and basic, and used liquid from a reaction. Hydrogen peroxide acts as a substrate for the enzymes. The reactants were the catalyst of different tissues and the variations of hydrogen peroxide. When combined, the product…

Put the hydrogen peroxide (In the jar) in the water, and the thermometer in the hydrogen peroxide 5. Once it reaches thirty degrees C test the solution. Test the activity by submersing the coffee filter in the potato solution for five seconds and dropping it in the hydrogen peroxide. With the timer for the coffee filter to sink and rise • Test the enzyme activity at forty degrees C 1. Fill the baby food jar with 2 ¾ tbsp. of hydrogen peroxide after cleaning 2. Fill a cooking pot…
